Finding a nice smartcard bezel was not easy. I found a nice metallic bezel from Amphenol, it is kinda expensive but it very nice indeed. The idea is to mount this bezel on an opaque black plexiglass piece and then mount this piece on the PC case. But first i have to find a way to fix the PCB onto the bezel's base...
This is the smartcard bezel from Amphenol
To mount the PCB on the bezel base i cut this plexiglass piece
It is somewhat longer than the PCB
I drilled 4 holes to screw the PCB on the plexiglass piece
I will be using sink-screws so i had to make the countersink
And this is how the pcb is mounted on the bezel's base...
Finishing the project
First i got a piece of black opaque plexiglass and marked the holes for the bezel
i removed those holes
This is how the bezel will fit
Then i put paper tape on the panel of my PC box
I put the plexiglass on the panel
and drew the required openings
Which i removed again...
I fixed the black plexiglass on the PC panel plexiglass with double side duct tape
@Giorgos Lazaridis Yeah, like I said, it'll work... mostly. If you take a look at TPC 12 on the ADG714 datasheet, the frequency response at ~500 MHz is going to be around -8 dB. The maximum attenuation of a USB cable is basically the same as that ( http://www.usb.org/developers/presentations/pres0410/2-2_SSUSB_DevCon_PHY_Heck.pdf ) - so essentially, you've basically just put in a long USB cable.
So long as you're talking about devices that are attached with, say, like a 1' cable or something like that, you won't notice basically anything. It's all just a question of how much margin you have left.
@Pat this was one of my concerned, it works ok until now, and i have test usb devices like external HDD (which i copied some 300GB of data with no problem) and also my camcorder uses the USB for the video. Nevertheless, have order relays with 4p2t if the adg fails or have slow data transmission.
"I'm not sure if the ADG714 can be used for USB applications."
No, it can't. It's the bandwidth that matters, not the on-resistance. It has a bandwidth of 155 MHz, which is way below USB spec. This is because the ADG714's input/output capacitance isn't 6/4 pF: I'm not sure where you got that from (the digital input/output capacitance is 3/4 pF respectively). Its on capacitance is *22* pF. This is way, way too high: on a 50 ohm input that's a critical frequency of ~150 MHz.
Switches designed for USB (like the FSUSB46) have on capacitances more like 4 pF, leading to a bandwidth of well greater than 480 MHz.
This design will work... some of the time. Probably mainly with short USB cables and devices that are well within USB spec. Definitely with low-speed USB devices. But high-speed USB devices could easily struggle since you're probably tacking on at least ~6 dB of attenuation.
